And With Mflash
I have the same problem.
First my phone came with viruses, and I wrote one firmware that is available to flash on the net using CMD and it flashed smoothly, but my phone had camera problem, only the front camera worked. Then I found another flashfile which is of different type and needed to be written using another method. When I wrote that Hisense-u971-13 firmware using QPST now phone half dead like some LG phones and detected only as Qualcomm HS-USB QDLoader 9008. When trying to write firmware I have always the same problem, but the address of flash writing failure is not the same always when trying to write.
Any advice how can I revive this damn phone?
Thanks
I see everywhere enter the mode download but do not see images or how to do it at the most is that I can get in diagnostic holding (vol +) + power, hence connect the USB, but it is still not the download mode. the fastboot only have the Chinese rom, hence got the European but is at QPST, need to restore the operation of the camera

My problem is I think I lost Recovery mode, I can`t turn on Recovery mode, only Flashboot mode on my device.
Can I install custom Recovery mode while my device have locked bootloader? Or how to fix?
Problem #2.
I have turned on USB Debugging, but when connected to pc I don`t see it at notification bar in device, in the same time some pc software doesn`t recognize the device, but on the other side it mostly does!
Waiting for response!
Solved it by MIUI forum guide - how to flashboot newest official Stable MIUI ROM with the right drivers for PC, all working now perfectly.
Man, can you send me the link used to solve your problem? I'm getting mad about the Debugging issue! ¬¬

Ulefone U007 - Mobile Phone Dead!

Hello,
I need help to recover my phone.
I've flashed my Ulefone U007 several times to update to a newer version.
The last time, I've installed without errors, but with time, the applications started to show errors, others disappeared (Marketplace, calculator, calendar, ... for example). I flashed the phone again with SP Flashing Tool, but something went wrong and my phone is dead since. The SP Flashing Tool doesn't detect my phone any more and gives me an error

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The phone doesn't show battery animation when I charge it, No light or vibration when I power on, I've tried "power"+"volume up" or "power"+"volume down", and nothing happen. Can't get to the recovery menu.
I'm using Windows 10. I think something inside the mobile is still alive, because when I connect the mobile in the USB of my computer shows a MediaTek USB Port (COM4) on the devices.
I'm guessing that the bootloader or disk partition is corrupt.
Any help will be appreciated.
Thanks in advance.
Regards.
